This paper presents an Internet-based open approach to laboratory instruction. In this article, the author talks about an open laboratory approach using a multi-user multi-device remote facility. This approach involves both the direct contact with the computer-controlled laboratory setup of interest with the students present in the laboratory…

A project involving the synthesis of several naturally occurring copper double salts using simple aqueous conditions is reported. The ions present in the compound are analyzed using colorimetric, gravimetric, and gas-analysis techniques appropriate for the first-year laboratory and from the percent composition, the empirical formula of each…

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

An environment appropriate for activity-oriented science is one that contains sufficient work space, equipment, and materials for students to practice and master the essential elements. This publication was developed to aid Texas school administrators, teachers, and architects to upgrade existing science facilities or plan new ones for…

Unified Technical Concepts (UTC) is a modular system for teaching applied physics in two-year postsecondary technician programs. This UTC laboratory textbook, the second of two volumes, consists of 45 learning modules dealing with basic concepts of physics. Addressed in the individual chapters of the guide are the following topics: force…

Describes a summer course in chemistry conducted by college teachers for children aged 9 through 12. The children were provided with simple laboratory equipment and performed actual experiments and recorded the results. A few demonstrations were given, but lecturing was kept to a minimum. (MLH)

Describes how to convert a wooden block into an apparatus to study friction. (LS)

Describes a project-oriented high school chemistry course that utilizes laboratory units in which the students make a practical product, such as soap, thus exposing them to career possibilities. (MLH)

Describes the construction and use of a simplified apparatus for fermentation studies. (LS)

Describes the investigations of the decomposition of a diazonium salt by the action of light. (LS)

Describes an experiment designed to develop an understanding of the basic acid neutralization reaction of sodium bicarbonate, calcium carbonate, and aluminum hydroxide gel. Presents a procedure for the determination of reaction rate for an antacid in vitro and provides sample data for this determination. (GS)
